NfV (Network Function Virtualization)SP-driven Initiative ETSI architecture

Enablers

• Hypervisor and cloud computing technology

• Improving x86 h/w performance

• Optimised packet processing and coding techniques

• Network industry standardising on Ethernet

• SDN based orchestration

Value Proposition

• Shorter innovation cycle

• Improved service agility

• Match capacity with actual demand

– NB : may reduce CAPEX / OPEX

NfV = Transition of network infrastructure services to run on virtualised compute platforms – typically x86
